PowerLAB, Another ATX power supply for Lab

Last crawled date: 4 years, 3 months ago

Another ATX Power supply things.
Updates:
26/01/2020:Print ready! update facade after test. update stl files. add Step file, update drawings. (V7)
13/01/2020: update stl file, first print seems to be ok, waiting some parts for the wiring, back of the front face migth be change.
11/01/2020: update ATX dimension, remove wrong STL files, printing test ongoing.
Why I do this:
It is usually difficult to know the dimension of things (no 2D drawings with cotation), so I decided to make one with 2D drawings.
It is an excellent excercise to learn Onshape.
It is fun!
